Testing is set to begin at the Windshear facility in Concord, North Carolina, on Thursday evening local time, with the Ford Mustang, Chevrolet Camaro and Toyota Supra under evaluation.<\/p>\n
The cars were prepared in Australia by homologation teams Triple Eight, Team 18 and Walkinshaw Andretti United and dispatched to the US via sea freight in late September.<\/p>\n
Each HT has been allowed five staff at the tunnel this year, two engineers, two mechanics and one addition of their choosing, with Supercars staff and contractors completing the crew.<\/p>\n
Some flew out directly from the Adelaide Grand Final, while others were afforded a brief trip home to see family before heading Stateside.<\/p>\n
It marks a return to Windshear for the category following two runs over the 2023\/24 off-season, and the first with the distinct Supra shape in the mix.<\/p>\n
The Team 18 Camaro will be used as the baseline for the test, to which a Triple Eight-tweaked Mustang and the WAU Supra must be matched.<\/p>\n
Overseeing it all is Supercars motorsport boss Tim Edwards, who admits getting all three cars inside the designated \u201cparity box\u201d will be a tough ask.<\/p>\n
\u201cWe are trying to throw a dart in the centre of the dartboard and hit a bullseye,\u201d Edwards told Speedcafe.<\/p>\n
\u201cIt is a very small box and all of us are aware that it\u2019s going to be a huge challenge to get the three cars into the box.\u201d<\/p>\n

While the goal of getting the three cars to produce the same downforce and drag numbers sounds simple enough, they must do so across various ranges.<\/p>\n
A 20-page document \u2013 beefed up significantly since the previous trip to the tunnel \u2013 governs the testing and features a matrix of requirements.<\/p>\n
\u201cThere\u2019s a massive table of different ride heights, yaws, pitches, etcetera, and then there\u2019s different weightings based on the amount of time you spend in all these areas,\u201d he said.<\/p>\n
\u201cWe\u2019re older and wiser, and we\u2019ve been running these cars for two more years since the last time we did it, and cars aren\u2019t being run at the same ride heights that they were two years ago.<\/p>\n
\u201cWe\u2019ve been running laser ride height sensors over the last few rounds, in eight cars across different teams, capturing that information.<\/p>\n
\u201cSo we\u2019ve got a way better picture of where everybody\u2019s running the cars these days compared to where they were running them in 2023.\u201d<\/p>\n
Supercars has put months of effort into refining the process, working alongside the three HTs and its aerodynamic partner Dynamique.<\/p>\n
